Question

помогите пожалуйста(((

Answer 1

1. a)  $frac{m-8}{5x}: frac{m^{2}-64 }{15m^{2}}= frac{m-8}{5m}*frac{15m^{2}}{m^{2}-64}=(m-8)* frac{3m}{(m-8)*(m+8}= frac{3m}{m+8}$
2. $frac{2^{5}*0,5^{-6}}{16^{3}}= frac{2^{5}}{2^{12}*0,5^{6}}= frac{1}{2^{7}*0,5^{6} } frac{1}{2^{7}* (frac{5}{10})^{6}}= frac{1}{2^{7}* frac{1}{2^{6}}}= frac{1}{2}$
